Rapid 15-minute Covid Antigen Test

Testing on site with 15 minute turn around time. These tests are performed with a nasal swab. The test detects viral protein in an actively infected person. FDA EUA clearance.

Covid 19 RT-PCR Viral Testing

RT-PCR viral testing is used to diagnose active infection; Tests are available with a 24-48-hour turnaround time from lab sample receipt.

Covid 19 IgG and IgM Antibody Testing by ELISA 

IgM antibodies: IgM antibody levels rapidly increase within 3-7 days after viral infection.
IgG antibodies: IgG antibody levels rise within 10-17 days and persist, indicating potential immunity.

Antibody tests check your blood by looking for antibodies, which can show if you had a past infection with the virus that causes Covid-19. Antibodies are proteins that help fight off infections and usually provide protection against getting that disease again. Depending on when someone was infected and the timing of the test, the test may not find antibodies in someone with a current COVID-19 infection. Requires a blood draw. 1-2 day turnaround time.
